Weird Linux amd64 abi trickery (raw.githubusercontent.com)

This Code should calculate the "Frobenius number". When the arguments are missing its exiting.

This is done by using the Linux abi in which the return register of asm_exit_ret is used to set the rax register and the input 'i' to set the rdi register.
